Abstract

Abstract: Background: Prevalence of early repolarisation ECG pattern (ER) has been repetitively determined in adults, but has not been reported in large unselected children populations so far. Methods: ECG from 1000 successive healthy children from birth to 17 years old were prospectively recorded and analyzed. ER was defined by ≥ 0.1 mV J point elevation in at least two contiguous inferior or lateral ECG leads. Correlations with age, gender, ethnic origin, physical activity, Sokolow index and heart rate were performed. Results: Prevalence of ER pattern was 23, 6% (95% CI 21–26.2%) and increased after 8 years of age. ER was independently correlated to a non Caucasian origin and a higher Sokolow index, but not to gender or level of physical activity. ER was independently correlated to an older age in children with heart rate < 100 bpm, and to a slower heart rate in children ≥ 8 yo. Conclusion: ER is present in a quarter of children of various age and is related to ethnic origin, an older age, a slower heart rate and a higher Sokolow index.
